I want to search for "foo" in "foo bar foo bar foo bar foo bar" starting
from the end, my first match would be ^
and not ^
But I guess all the smart algorithms would need to redo preprocessing
anyway, so reversing both strings seems like the way to go, even if that
might have performance implications.
